System for conducting the identification of bacteria in biological samples

Abstract

The present invention relates to a system for conducting the identification and quantification of micro-organisms, e.g., bacteria in biological samples. More particularly, the invention relates to a system comprising a disposable cartridge and an optical cup or cuvette having a tapered surface; an optics system including an optical reader and a thermal controller; an optical analyzer; a cooling system; and an improved spectrometer. The system may utilize the disposable cartridge in the sample processor and the optical cup or cuvette in the optical analyzer.

AI Technical Summary

Benefits of technology

[0008]The system of the invention streamlines the current system for obtaining specimen results. The system is environmentally friendly, enables a rapid diagnosis, results are consistent, no reagents are needed, and there is a multifunctional diagnosis. According to one embodiment disclosed in commonly owned PCT Application US2008 / 079533, biological samples are contained within disposable cartridges which hold four disposable components, i.e., a centrifuge, two pipette tips with a different volume, and an optical cuvette. The cartridges are bar coded and tied in with the patient's ID. The cartridges are inserted in a magazine which is then inserted into a sample processor which processes the specimens. The prepared specimens are transferred into the optical cuvettes and then the magazine is inserted into an optical analyzer which analyses the specimens. The optical analyzer analyses and generates the complete results enabling ultimate treatment of the bacteria. The system does not require a sophisticated operator and gives rapid results.

Problems solved by technology

In general, current-day practice for identifying micro-organisms, e.g., bacteria in urine samples, involves a complex, lengthy, and expensive process for identifying and specifying micro-organisms in microbiology labs.

This entire process generally takes 11 steps and 50 hours to obtain specimen results and the process is labor intensive.

However, the reference fails to disclose any specific description / design of the cuvettes.
